Sessions consisted of once/week instructor-led practice and once/week home practice. Particular attention was given to poses that emphasized upper body strength and flexibility, while avoiding significant time with the upper extremity (UE) in a dependent position; OBJECTIVES: To assess the feasibility, safety, and initial estimates of efficacy of a yoga program in postoperative care for women at high risk for breast cancer-related lymphedema (BCRL); OUTCOME MEASURES: UE volume was assessed through circumferential forearm measurement, which was converted to volume using the formula for a truncated cone. Range of motion (ROM) was assessed for the shoulders, elbows, and wrists, using a standard goniometer. UE strength was assessed for shoulder abduction, elbow flexion, wrist flexion, and grip using a dynamometer; RESULTS: Twenty women completed the yoga intervention, with 17 returning for final assessment. Mean age was 52 (+/-9.1) years and body mass index was 24.8 (+/-5.1) kg/m2. Postintervention, mean volume in the at-risk UE was slightly reduced (p=0.397). ROM for shoulder flexion (p<0.01) and external rotation (p<0.05) significantly increased bilaterally. Shoulder abduction ROM significantly improved for the unaffected limb (p=0.001). Following intervention, strength improved on the affected side for shoulder abduction and grip strength, and bilaterally for elbow flexion (p<0.05 for all); SETTINGS/LOCATION: Patients were recruited from the University of California, San Francisco Carol Franc Buck Breast Care Center; SUBJECTS: Twenty-one women were enrolled in the study. Women were >18 years of age, had undergone surgical treatment for breast cancer, and were at high risk for BCRL UR - https://dx.doi.org/10.1089/acm.2017.0145 ER -
